I'm looking for a way to make thumbnails from jpgs without using the ImageCreateFromJPEG function.

Is it possible?

We have php 4 but don't have gd compiled... and don't want to take the time...lol

I don't believe so, but I think imagecopyresized could be used to create thumbnails.

I've not used it myself so I'm not entirely sure though...

so that still requires gd... we might have to bite the bullet then and just recompile php....

klewlis, if your server has the convert command, you might try that. It works on my home server, for some reason it doesn't work on guardian, but it should work for you.

you pass the convert command to a shell using a passthru, exec, or system command.

passthru('convert image1.jpg -resize 200x400 image1_thumb.jpg');

make sure that the permissions on whatever folder the thumbs are to be created in are ok.
not sure if that's 100% correct; look around on google for help with the syntax.

'convert' is part of the Image Magick program.

hey gneato, would you be able to find me your exact line? I've found a few on google but can't seem to get any to work, and image magick's site seems to be down...

thanks!

$im = the path and filename of the original
$thumb = the path and filename of the thumbnail to create

passthru("convert ".$im." -resize 231x231 ".$thumb);
